when I tried to change outfits in the toilet of a moving train.
I had my t-shirt halfway over my head as a jolt made me ricochet around the tight space, culminating in my banging my head with some force on the sink counter.

from London to Newcastle once and the woman opposite me was putting her make-up on for literally about 2 hours. She looked much worse at the end than she did at the start. The whole thing was actually really sad.
